Answer 1

function currentLine(katzDeliLine) {
    if (katzDeliLine.length > 0) {
        var textToPrint = "The line is currently: "  

        for (var crrLine = 0;  crrLine < katzDeliLine.length; crrLine++) {

        textToPrint = textToPrint + (crrLine + 1)+". " 
        +katzDeliLine[crrLine]+","

}


return textToPrint.replace(/,\s*$/, "");
} else {
return "The line is empty"
}
}

var lineofpeople = ["katrina", "kevin", "vincent"]
console.log(currentLine(lineofpeople));
